javascript - JSON.解析: unexpected non-whitespace character after JSON data at line 1

Question

我正在使用一个非常简单的 JavaScript(AngularJS，但这不相关)，例如:

app = angular.module('app', []);
app.controller("NavCtrl",function($scope,$http){
    var serviceBase = 'api/';
    $http.get(serviceBase + 'orders').then(function (results) {
        $scope.categories = results.data;
    var total = 0;
    for(var i = 0; i < $scope.categories.length; i++){
        var categories = $scope.categories[i];   
    }
    });
});

HTML

<div class="col-md-3" ng-controller="NavCtrl">
      <div class="sm-st clearfix">
      <!--<span class="sm-st-icon st-red"><i class="fa fa-check-square-o"></i></span>-->
       <div class="sm-st-info">
       <i class="fa fa-square"></i>
       <span>Sander</span>
       <p>1 minutes</p>
          <ul>
            <li ng-repeat= "p in categories">
                  {{p.orderID}}
            </li>
          </ul>
      </div>
   </div>
</div>

现在我收到错误:

JSON.parse: unexpected non-whitespace character after JSON data at line 1.

我的 JavaScript 或 PHP 是否有问题？如何修复？ 我认为我传递的代码或数据没有任何问题......

Answer 1

您不应该在 JSON 对象数组上使用 JSON.parse，请改用类似以下内容的内容:

for (var i = 0; i < jsonData.length; i++) {
    console.log(jsonData.orderID);
}

此外，我在您的 JSON 结果中看不到任何字段 categories。
